Scratch-injured human umbilical vein endothelial cells (HUVECs) supernatants induced MMP-9 expression in THP-1 cells. (a) MMP-9 protein expression in control cultures and in cultures treated with the supernatants of scratch-injured HUVECs for 1, 3, 6, and 12 h. (b) Quantitative data for (a). compared with control; compared with rest groups.
